SPECIFICATION forming part of Letters Patent No. 7 95,120, dated July 18, 1905.

Application filed July 25, 1904:. Serial No. 218,023.

To all whom it may concern.-

Be it known that we, WILLIAM M. HARRIS and AUGUST F. DONALDSON, citizens of the United States, residing at Mansfield, in the county of Richland, State of Ohio, have invented certain new and useful Improvements in WVindoW-Strips, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a Window-strip, and particularly to a metallic packing-strip adapted to travel in a groove upon a sash to effect an air-tight joint therewith and also to prevent rattling or movement thereof.

The invention has for its object to provide a construction embodying a plate of spring material secured at one longitudinal edge and provided at its opposite edge with a curved face adapted to contact with a sash and having an inturned outer edge to secure a broad hearing when the strip is compressed and prevent injury to the window-frame in the continuous use of the strip.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a perspective with parts broken away, showing the invention applied to a window-sash. Fig. 2 is a detail vertical section with the sash out of contact with the strip. Fig. 3 is a similar view with the strip under compression. Fig. 4 is a detail of the strip, showing the free end thereof terminating in a horizontal plane above the body portion; and Fig. 5 is a detail perspective of a portion of the strip.

Like letters of reference refer to like parts in the several figures of the drawings.

The letter A designates a window-frame of any desired character containing the usual sash A, which is provided upon its side and bottom rails with a groove A which may be of any character suitable for the purpose; but a preferred form thereof is herewith shown embodying opposite inwardly-beveled walls connected at the base of the groove by a fiat or straight portion A The strip B may be formed of any suitable spring material, preferably metal, and is provided along one of its longitudinal edges with securing means B, by which it may be attached to the sill or side of a window-frame, while its body portion is preferably slightly curved, as indicated at B in order to secure the desired elasticity or spring of the material thereof. The free longitudinal edge of the strip is provided with a curved portion or face B extending away from the body of the plate, and the outer free edge 13 of this portion is turned inwardly, so as to present a broad bearingsurface when the strip is compressed, as shown in Fig. 3, and also to obviate the scarring or cutting of the frame in the compression of the strip, which would occur if the free edge of the curved portion extended directly downward. It will also be observed that the inwardly-turned edge B" of the curved portion terminates above the body B, so that the first action of the contact of the sash is to bring the body 13 into contact with the frame, exerting the spring tension thereof, and a further movement of the sash toward the strip permits the curved portion to exert a supplementary spring action and expand laterally in its downward movement, thus fully filling the grooves,as indicated by full lines in Fig. 4. This expansion causes a slight travel of the free edge of the strip within the sashgrooves, and the flat or straight portion A of the groove is provided to permit this movement within the grooves without binding, while the frictional contact between the strip and groove is reduced to a minimum, owing to the 'rved construction of the strip in its relation to the angular groove.

It will be obvious that the spring-body of the strip insures a constant pressure and per-' fect contact between the side strips and the sash, which effects an air-tight joint and also prevents rattling or other movement of the sash in the frame, while when the sash is forced downward upon the sill the tension of the body of the strip is supplemented by the expansion of the curved free edge thereof within the groove, so as to effect a perfectly tight joint at this point. The free edge of this curved portion being bent at an angle removes the raw edge of the metal to prevent injury to theframeand also insures a smooth uniform outer edge having the most desirable bearing contact when the strip is compressed, while in this compression the angular form of groove permits the expansion of the curved edge of the strip without friction and also offers less resistance to the movement of the sash, as the bearing contact between the'strip and groove is at a single point upon the flat surface of the groove, which cannot occur in the use of an angular strip having an extended surface contact. It has also been found desirable to apply a coat of heavy paint to the lower surface of the strip, which aids mate.

rially in effecting an air-tight joint. The strip is herein shown as applied to the frame and the groove in the sash, but it will be obvious that a reversal of this relation may be made.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described our invention and set forth its merits, what we claim, and desire to secure by Letters Patent, is

1. A window-strip comprising a plate of spring material secured at one edge and provided at its opposite free edge with a raised contact-face extending away from the body of the plate and terminating in an inturned outer edge disposed in a plane substantially parallel to and at one side of the body of the plate, whereby said contact-face is adapted for expansion independent of the body ofthe plate when under compression.

2. A windowstrip comprising a plate of spring material secured at one longitudinal edge and provided at its opposite free edge with a curved face extending away from the body of the plate and adapted to expand laterally to and independently thereof, and a cooperating member provided with a groove of greater transverse diameter than the curved face and a straight base to contact with said face. i

In testimony whereof we affix our signatures in presence of two witnesses.
